I remember watching this movie as a child, too. It did not hold the important place in my heart that it does in yours, but I remember it very vividly and when my niece started watching it (when she was maybe 4?) I found myself remembering far, far more of the lyrics and dialogue that I would have thought. It was fun.

Interestingly, my experience with Liesl involves childhood baggage - my mom really spoke negatively about growing up and I had a lot of fear of Becoming A Woman, so I found Liesl's storyline kind of scary. She falls in love, yes! But kissing is kind of icky, and the dude turns out to be a Nazi! Etc. Still, that gazebo scene is familiar and strangely comfortable for me because it is delightful if you ignore the lyrics, it's true. :)
